9 Cleaning and Drying the Measuring
Cell
Hint:
Cleaning should be performed with 2 cleaning liquids. Cleaning liquid 1
dissolves and removes residues, cleaning liquid 2 removes cleaning liquid 1
and is easily evaporated by a stream of dry air in order to accelerate drying in
the cell. Both cleaning liquids should not react with the sample nor with each
other.
1. Fill the measuring cell with cleaning liquid 1 using a syringe with Luer tip.
Move the plunger of the syringe in and out several times. This creates gas
bubbles which improve the cleaning action.
Important:
• Find a suitable cleaning liquid 1 before the first measurement.
• Cleaning liquid 1 should dissolve residues in the measuring cell.
• For water-soluble residues water can be used.
• Do not use highly concentrated alcohol as cleaning liquid 1 for proteins,
sugar or similar organic residues because insoluble residues may form in
the measuring cell.
2. Remove cleaning liquid 1 from the measuring cell.
3. Fill the measuring cell with cleaning liquid 2 using a syringe with Luer tip.
4. Remove cleaning liquid 2 from the measuring cell.
5. Attach the air hose to the Luer injection adapter (see Fig. 9 - 1).

Hint:
Check that the air humidity does not exceed the limits given in Appendix A
and use a desiccator if necessary.
